REVERSIBLE WINDOW Application filed. February 25, 1927. Serial No. 170,995.

This invention relates to windows made reversible so that they can be Washed on both sides. In washing windows especially in large oflice buildings it is now the common practice of the window washer to get on the outside of the building, and in order to protect the occupant of the oflice from cold drafts in wintry weather both sash are usually closed while the work is being done. Such work is very dangerous to the washer and in view of my invention unduly exposes him. The object of my invention is to provide a sash the glass of which can be washed on both sides from the interior of the building without materially exposing either the occupant of the building or the workman-the sash being invertible by movement into the room and when inverted substantially closing the opening. A further advantage of my sash is that it can be inverted notwithstanding the window opening may be screened or barred on the outer side and notwithstanding there may be objects near the sill at the inner side of the window opening that might interfere with a sash otherwise constructed.

The invention is embodied in the example herein shown and described the features of novelty being finally claimed.

In the drawings- Figure 1 is a vertical section on the line I-I Fig. 4 showing my invention with the window in normal position.

Fig. 2 is a similar view with the glass frame turned over or inverted.

3 is a vertical section similar to Fig. 2 with the glass frame removed, or on the line III-III Fig. 4 looking to the right.

Fig. 4 is a horizontal section on the line IV-IV Fig. 1.

In the views 5 designates the ordinary casing. 6 designates the sash adapted to slide vertically as usual in the guides of the casing. 7 designates the glass carrying frame with alight or glass therein, said glass being designated 8 and secured with putty 9 or other suitable means.

The glass frame is suspended by a pair of identic links of bars 10 each pivoted at its upper end to the inner side of the upper en 13 in the vertical inner sides of the sash.

' The upper side of the glass frame is-provided with a spring actuated latch 14 that snaps into a suitable notch at the top of the casing to hold the glass frame closed in the sash when said frame is turned to normal position. The bolt of said latch is provided with a hook or eye by which it can be taken with the-fingers or,.if high, with a tool, to. withdraw the latch and pull the top of the glass frame downward.

When the glass frame is pulled down at the top the upper end movesoutward into the room while the lower end moves vertically upward it being held by reason of the engagement of the studs with thegrooves in the casing and by continuing this movement the glass frame turns over on the pivots 12 and is practically completely inverted when it); reaches the position shown in Fig. 2. The cut away portion at 10 of the links 10 prevents interference of the rollered studs with the movement of the links and a proper connection of the links. In this inverted posi-- tion the window is practically closed and presents the outer face of the glass at the inner side of the room for its most speedy and convenient washing and polishing and avoid exposing the occupants of the building and the washer to the wintry drafts or the washer to the danger of fallin to the ground below.

The invention can be used either in a single construction or with the more usual double or upper and lower sash as suggested in Figs. 1 and 2.

The sash and glass frame are preferably constructed of hollow sheet metal form, as shown, but the forms and materials of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

1. A window sash having therein a glasscarrying frame, a pair of links suspending whereby the glass-carrying frame can be said frame in normal sash-closing position in said sash, each of said links pivotally conneoted at a fixed point to the sash near the upper end of the opening thereof and to sub stantially the middle of a side of the glasscarryingframe, guiding grooves in the sides of the sash, and studs in the lower portions of the glass carrying frame engaging said grooves, whereby the glass-carrying frame can be swung and turned on said links from normal sash closing to substantially inverted sash closing position.

2. A window sash having therein a glasscarrying frame, a pair of links suspending said frame in normal sash-closing position in said sash, each of said links pivotally connected at a fixed point to the sash near the upper end of the opening thereof and to substantially the middle of a side of the glassoarrying frame, guiding'grooves in the sides of the sash and studs on the lower portions of the glass carrying frame engaging said groves, said links being cut away at their upper portions to prevent interference of said studs with the oscillations of said links,

swung and turned on said links from normal sash closing to substantially inverted sashclosing position.

GEORGE W. LINN.
